Abstract:
A multi-layer or multi-view video is encoded by encoding one of a picture in a first layer or view and a picture in a second layer or view coinciding at a switching point defining a switch between the first layer or view and the second layer or view. The other of the picture in the first layer or view and the picture in the second layer or view coinciding at the switching point is encoded as a skip picture. The embodiments thereby reduce complexity of encoding and decoding multi-layer or multi-view video having a switching point and reduce the number of bits required for representing encoded pictures coinciding at the switching point.
